ABSTRACT
Sub-Saharan African exports of horticultural and processed agricultural products are growing in line with
the major shift toward these products in world markets. Continued growth in such exports may be vitally
important for expanding returns from African agriculture and for increasing Africa’s overall exports.
Policy reforms such as reductions in the tariff escalation facing Africa, improvements in the productivity
of agricultural processing, and reductions in trade barriers within Africa and beyond would all further
stimulate exports of processed agriculture. While essential, expansion of these exports should be regarded
as complementary to—rather than a substitute for—development of other dynamic export sectors.

1. INTRODUCTION
Agricultural exports from Sub-Saharan Africa (SSA)1 include a much larger share of bulk agricultural
exports than is the norm on world markets, where processed products have come to dominate. In looking
at how Africa might move beyond traditional bulk exports and the resource-based exports that are also
disproportionately important in Africa, a few questions appear to be key. Should African exports move
into labor-intensive manufactures of the type that have dominated the export-led growth of Asian
economies from Hong Kong, Korea, and Taiwan (China), through China, Bangladesh, Cambodia, and
Vietnam (Page 2012; Newman et al. 2016b)? Should they pursue alternative approaches such as adding
value to existing agricultural exports or developing new high-value agricultural exports? Or should policy
makers undertake strategies to encourage entrepreneurs to look everywhere for opportunities, recognizing
that it will often be difficult to find successes, but that the rewards from identifying a highly successful
export are very great (Hausmann and Rodrik 2003; Easterly and Reshef 2010)?
While it is well known that the share of the agricultural sector in an economy typically declines
with economic growth, it is less known that the share of the agro-processing sectors in gross domestic
product (GDP) tends to increase as local consumption shifts from raw, starchy staple foods to foods such
as vegetables, fruits, and meats and as food consumed comes to embody more services (da Silva et al.
2009). We examine whether SSA is following this pattern and whether agricultural exports from Africa
are moving from bulk products to processed and horticultural goods. Given SSA’s current income, is this
an area in which Africa is lagging and potentially large gains can be made? Or are African exporters
already acting to exploit potential gains?
Export growth is vitally important for a wide range of reasons, as it promotes economic growth,
creates jobs (Calì and Hollweg 2017; Fukase 2013), and is a source of the foreign exchange needed to
import goods that cannot readily be produced locally. Domestic and international policies, however,
influence both the level and the mix of products that are traded. In recent years, the “trade in tasks” in the

new wave of globalization (Baldwin 2006, 2016) appears to have been creating new opportunities for African
countries to tap into export markets, as they enjoy a number of location-specific comparative advantages.
How should African governments act to influence the development of nontraditional exports, such as
those from agro-processing operations, or high-value export crops such as horticultural products, or both?
This paper analyzes the principal features of agro-processing and horticultural exports from SSA
and explores policy alternatives based on simulation analyses. We first provide a conceptual section
focusing on changing patterns of processing and exports (section 2). We then examine how the pattern of
exports from Africa compares with the pattern in other regions (section 3). Following that, we examine
the directions of trade in African agricultural exports and the patterns of protection facing, and imposed
by, African countries (section 4). Next, we turn to simulation exercises to examine the impacts of
potential reforms on exports of processed and horticultural exports from Africa (section 5). With this as
background, we turn to consider the options for policy makers in Africa (section 6). The final section
presents a brief conclusion (section 7).

2. CHANGING PATTERNS OF PROCESSING AND EXPORTS
Prior to the Industrial Revolution and the development of steam transport, international trade was very
limited because of high transport and communication costs. Some very high value-to-weight items such
as spices and gemstones were traded over long distances, but most foods and manufactures were produced
locally. Basic production patterns and income levels were very similar across the world.
As noted by Baldwin (2006, 2016), the first wave of globalization frequently involved the
production of raw materials in developing countries, with the processing of those products into final
manufactured goods generally taking place through vertically integrated production processes in
industrial countries. During this phase of industrialization, communications were not sufficiently well
developed to allow coordination of activities at a distance, and the capital needed for industrial
development tended to be most readily available in the industrial countries. This pattern of
industrialization appeared to generate many gains from learning-by-doing in the industrial countries and
to contribute to a major divergence in income levels, with incomes in the industrial countries rising far
above the levels in developing countries.
Developing countries, understandably, were unhappy with this model of industrial development
and frequently tried to develop their own integrated industrial sectors, often by creating incentives to
process the raw materials that they produced, as suggested by Alexander Hamilton in his “Report on
Manufactures” published in 1791 (McKee 1934). Unfortunately, this typically proved to be very difficult
to achieve without excessive cost and loss to the producers of raw materials. Even where plans and
prototypes of processing plants from other countries were available, it frequently proved difficult to
operate them successfully (Hausmann and Rodrik 2003).
During this first phase of globalization, the initial processing stages needed to preserve, or to
lower, the weight of raw material exports were established in producing areas. Activities of this type
include cotton ginning, processing coffee cherries into dry coffee beans, initial processing of tea, and
slaughter of livestock. Some export-oriented processing activities going beyond this stage were
4
undertaken in developing countries, such as the transformation of cotton into textiles in India and
Pakistan, but they were the exception rather than the rule. Sometimes, these activities were artificially
induced by imposing taxes or quantitative restrictions on exports of raw materials—frequently under the
banner of “value adding.” A key problem with this approach is that—unless the activity can be performed
efficiently in the country—the associated high processing costs reduce the amount available for payment
to the producers of the raw material. This is both inefficient and inequitable when the suppliers of the raw
material are small, low-income producers. Unfortunately, this problem was quite common when countries
sought to increase the processing of their commodities—whether for export or, more commonly, for
domestic consumption—because many processing activities were capital and skill intensive and difficult
to undertake economically in countries very poorly endowed with capital and skilled workers.
In recent years, changes in the costs and allocation of factors have created new opportunities for
developing countries in both industrial production and further processing of agricultural commodities.
Lower transport and communication costs have made it possible for more parts of the production process
to be conducted in different locations, depending upon the competitiveness of the particular activity in
that location. Production of garments, for example, may involve growing cotton in West Africa where
agro-ecological conditions are particularly suited; making yarn and fabric (likely using blends of cotton
and other fibers) in China; assembling garments in Bangladesh; and enabling the transfer of information,
such as the designs for clothes and the authorization of production samples, to take place over great
distances. To exploit cost advantages created by these developments, firms from more advanced countries
are increasingly willing to bring the capital and knowledge needed for successful production via foreign
direct investment. This can obviate the very long process of learning otherwise needed to establish an
entirely new export activity (Hausmann and Rodrik 2003).
This new approach to production has opened up opportunities for developing countries not
available under the earlier approach to industrialization. Countries such as China, Vietnam, and
Bangladesh have developed export-oriented manufacturing systems that are deeply engaged in this
production system. Thailand has been very active in agro-processing, frequently using domestically
5
produced products but sometimes using imported inputs. This new form of industrialization has been
associated with a dramatic change in the distribution of world income, with countries that have engaged
in this process raising their average incomes and lowering poverty rapidly. Unhappiness about this
approach to development appears to be emerging in high-income countries, based on perceptions about
loss of manufacturing jobs to developing countries, although the evidence suggests that automation has
been a more important contributor to that phenomenon, and the decline in the share of manufacturing is a
global phenomenon.
The unbundled approach to global value chains involves much greater transfer of materials than
the traditional approach and hence is more demanding of logistics than traditional approaches. Issues such
as low transport costs and smooth customs clearance become important for the organization of
production. Once efficient logistics are in place, however, countries with suitable agro-ecological
conditions can potentially produce high-value products, such as cut flowers and fresh vegetables, which
formerly needed to be produced near their point of consumption. In this case, the logistics and trade
facilitation are also vitally important, given the high costs of delay. African producers of products such as
green beans, cut flowers, and fresh fruit appear to have seized some of these opportunities.
A recent improvement in economists’ approaches in the analysis of exports involves a recognition
of the diversity of experience by firms and with particular products. While trade theory did not explicitly
consider firms until the 1990s, the availability of transaction-level data revealed striking heterogeneity of
firms, with most exports accounted for by a surprisingly small share of firms. Further, these firms tended
to be more productive than nonexporting firms even when they began exporting—in contrast with the
traditional model in which firms learned by doing in the very different business environment facing
exporting firms. Only the most productive firms also tended to export multiple products and to multiple
export markets. While these findings were originally established for industrial countries (for example,
Bernard and Jensen 1995), they were quickly confirmed for developing countries (Clerides, Lach, and
Tybout 1998) and subsequently for exports of processed agricultural products (Gopinath, Sheldon, and
Echeverria 2007).
6
In Africa, considerable evidence has emerged that exporting firms are—as in other regions—
more productive and pay higher wages than nonexporting firms (Bigsten et al. 2004; Van Biesebroeck
2005; Brambilla, Chauvin, and Porto 2015). However, there are also indications that firms continue to
benefit from learning-by-doing after entering export markets (Bigsten et al. 2004; Mengistae and Pattillo
2004; Van Biesebroeck 2005; Newman et al. 2016a). Using firm-level panel data from three SSA
countries, Mengistae and Pattillo, in particular, find that the productivity of exporting firms grows
10 percent faster than that of nonexporting firms. A recent paper studying the case of Ghana by Mulangu
and Olarinde (2016) finds evidence of learning-by-doing, but no evidence of higher-productivity firms
selecting into exporting. It also concludes that the fixed costs associated with starting exports to African
countries are lower than those to other markets—suggesting that intra-African exports may provide an
opportunity for more firms to export, and to reap the productivity gains associated with exporting.
Another recent perspective on developing-country exports has come from the realization that
exports from most countries are dominated by a relatively small range of specific products (Hausmann
and Rodrik 2003). This is the case for even very large countries such as China and India for which only
one six-digit product (unrefined petroleum) appears on the list of top-25 exports in both countries
(Dimaranan, Ianchovichina, and Martin 2007). Easterly and Reshef (2010) find that exports from several
African countries are dominated by a small number of “big hits” with large export shares.
Whether African exports are highly specialized or not has important implications for the volatility
of export returns because highly concentrated export bundles are much more likely to be volatile than
more diversified export bundles. Adding processed agricultural exports to an export bundle dominated by
something else—such as resource exports—may reduce volatility. However, switching from exporting a
raw product to exporting the same product in processed form might not lead to a substantial reduction in
export volatility, if the price received for the processed product is heavily influenced by the price of the
raw material. Diversifying from agricultural and resource products to manufactures seems likely to
provide the largest gains from diversification.
7
Another factor influencing export outcomes is whether markets for particular products are
expanding or contracting. When markets are growing, prices are more likely to be buoyant in order to
provide an incentive for additional resources to flow into the sector. In shrinking markets, competition
between suppliers—and particularly suppliers with large fixed investments in production—is more likely
to put downward pressure on prices. With income growth, consumers are likely to move from purchasing
raw agricultural products to consuming products with additional embedded services (da Silva et al. 2009).
For this reason, it seems more likely that markets for processed agricultural products will grow more
rapidly than markets for raw products when incomes rise in consuming countries. Demand for horticultural
products such as tropical fruits and fresh flowers is also likely to grow relatively rapidly as incomes rise,
potentially making the exports of these products grow faster than staple agricultural products.

3. GLOBAL PERSPECTIVE ON AGRICULTURAL PROCESSING AND HORTICULTURAL EXPORTS
In this section, we first examine the evolution of exports from SSA and other regions. Figure 3.1 shows
the composition of Africa’s exports of goods and services, divided into agriculture, resources,
manufactures, and services. Figure 3.1 reveals the small share of agriculture in African exports at around
10 percent, which is lower than the 12 percent accounted for by exports of nonfactor services. This low
share of agriculture in total exports suggests that the opportunities for expanding total exports by
processing existing agricultural exports—some of which are already processed—are likely to be more
limited than where exports of unprocessed agricultural products account for a large proportion of total
exports.

the export structure of SSA with global export patterns using an index of revealed comparative advantage
(RCA) (Balassa 1965). This index compares shares of exports from SSA with the corresponding global
shares. Table 3.1 indicates that the RCA of Africa in agriculture has fallen from 2 to 1.5 since 1992. The
RCA for resources exports has also declined—from 4.5 to 3.2, while that for manufactures has risen
slightly, from 0.4 to 0.5. These results suggest that African exports have moved somewhat closer to the
world average over the past two decades.

Notes: Countries are classified as oil exporters if the share of fuel exports relative to gross domestic product is above 10 percent.
SSA = Sub-Saharan Africa.
For non-oil exporting African countries, we see a similar pattern of decline in the RCA for
agricultural and resource products, although the agricultural product RCA is substantially above that for
the region as a whole. The increase in the RCA for exports of manufactures is much stronger for the non–
oil exporters, rising from 0.5 to 0.8.
Between 1988 and 2014, world agricultural exports grew from $83.4 billion2 to $1,532 billion
while SSA’s agricultural exports increased from $2.7 billion to $44.3 billion (the UN Comtrade
System). As a result, SSA’s share in world agricultural exports declined from 3.3 percent in 1988 to
2.9 percent in 2014. We distinguish among agricultural products using the Regmi et al. (2005)
definitions of bulk, semiprocessed, and processed agricultural products, plus horticultural products. As
2 All figures are in US dollars. In 1988, agricultural exports were 9.6 percent of world exports of goods and services, and
declined to 7.2 percent in 2014.
10
noted by Liapis (2011, 12), bulk and horticultural products are tied strongly to geographic conditions,
while semiprocessed products such as sugar or cocoa products and processed products such as meat and
chocolate are less geographically linked and could potentially be produced using inputs from other
locations. With these definitions, we see a sharp difference between Africa and the world as a whole.
As shown in Figure 3.2, for the world as a whole, bulk agricultural products account for a small and
declining share of agricultural exports—decreasing from 25 percent in 1988 to 17 percent in 2014. By
contrast, processed and semiprocessed agricultural products accounted for almost three-quarters of
global agricultural exports by 2015. Horticultural exports accounted for around 12 percent of global
agricultural exports in 2014.
For Africa, the corresponding patterns are quite different. The share of bulk agricultural exports
also declined, but from around 60 percent to 42 percent in 2014, leaving these exports still as a large
share of total agricultural exports. The share of processed and semiprocessed agricultural products rose,
but only to 35 percent by 2015. If African countries are relatively abundant in raw agricultural goods
and scarce in capital, a larger share of bulk exports relative to processed agricultural products is consistent
with the Heckscher-Ohlin-Samuelson model, which predicts that countries export products that use
relatively abundant factors of production. The share of horticultural exports rose from around 10 percent
in 1988–1989 to 22 percent in 2014. It seems clear that African exporters are adjusting to the changes
in the world markets, but doing it in a distinctively African way. In particular, the expansion of
horticultural exports suggests that Africa has seized new opportunities, for instance, in becoming
integrated into global agricultural value chains in flowers and horticultural crops (Minten, Randrianarison,
and Swinnen 2009).

To look in more detail at agricultural exports from Africa, we consider individual six-digit
products using the Harmonized System product definitions—the finest for which internationally
comparable measures are available. In Table 3.2, we examine these products for 10 focus countries and
for SSA as a whole. The table shows the export value share for each of the top 20 agricultural exports, the
share held by the top 20 products, the number of agricultural exports, and the numbers equivalent of the
Herfindahl index for agricultural exports (Adelman 1969). This numbers-equivalent measure—measured
as 1
∑𝑆𝑖2 where Si is the share of each product in the total—shows the number of equally distributed exports
that would provide the same degree of diversification as the observed set of exports, assuming
independent and identically distributed volatility for each commodity export.

Table 3.2 shows that agricultural exports from African countries tend to be highly concentrated,
with the largest export having a very large share of total agricultural exports, and subsequent exports
having much smaller shares.3 Consistent with this, the top 20 exports accounted for 80 percent or more of
export returns in each of our focus countries except South Africa, and more than 90 percent in five of our
focus countries. While each country has what appears to be a large number of agricultural exports
(between 208 and 655), the very large shares accounted for by the top products mean that these export
baskets are much less diversified than they might at first appear. The numbers equivalent of the
Herfindahl index suggests that, for instance, the 362 agricultural exports from Ghana provide the export
market diversification that would be provided by having just three equally distributed agricultural exports.
The 520 and 208 agricultural exports from Kenya and Mozambique, respectively, provide little more
diversification, being equivalent to only five identically distributed products. In contrast, the agricultural
export baskets of Senegal, Tanzania, and South Africa are much more diversified, being equivalent to 17,
18, and 44 products, respectively—numbers which should provide considerable diversification. The lack
of diversification in African exports is consistent with the findings of other studies. For instance,
calculating the global geographic diversification index (De Lombaerde and Lapadre 2012) and the global
sectoral diversification index, Bouët, Cosnard, and Laborde (2017) find low levels of product and partner
diversification for African exports.
The last two columns of Table 3.2 show the results for SSA as a group for agricultural goods that
went to the world and to SSA, respectively. The exports that went to SSA turn out to be somewhat more
diversified: SSA’s top 20 exports to the world and to the SSA accounted for 56 percent and 48 percent,
respectively, while the corresponding indexes were 33 and 54. This may reflect the relatively low entry
costs into exporting to SSA countries reported by Mulangu and Olarinde (2016). It may also reflect a
tendency to re-export high-value processed agricultural items—often imported from outside Africa.
3 Following Easterly and Reshef (2010), we plotted the log of the rank for each export against the log of its export share and
confirmed that these distributions followed a power law, under which a small share of products accounts for a very large share of
exports.

Table 3.3 shows the composition of the top 20 exports for SSA as a group to the world and to
SSA. Table 3.3 also categorizes SSA’s exports into bulk (B), horticulture (H), and processed (P) agriculture,
which are shaded in blue, green, and pink, respectively. In terms of SSA’s exports to the world (first
panel), the five top items are dominated by bulk exports—cocoa beans, coffee, unmanufactured tobacco,
sesamum seeds, and black tea. Fresh cut flowers and horticulture products such as cashew nuts and fresh
fruit (including apples, oranges, and grapes) also made the list. Processed agricultural goods such as
cocoa paste, cocoa butter, and frozen fish may reflect the availability of local raw materials.
The second panel of Table 3.3 reveals the quite different nature of the top 20 exports that were traded
within SSA, with a disproportionately high share of processed goods, including such items as cigarettes and
tobacco, frozen fish, sugar, palm oil, beer, soup, flour, milk and cream, and mineral water. In value terms,
nearly two-thirds of the agricultural products traded within SSA in 2013 were processed agricultural products.
Given the diversity of African countries, looking at SSA exports in total may well miss important
details. Are, for instance, exports of horticultural products from just a few countries? Appendix Table A.1
shows the composition of the top 20 agricultural exports for our 10 focus countries. The importance of
coffee, cocoa, and tea stands out at the country level: coffee (090111) was the most important agricultural
export item for Ethiopia, Rwanda, and Uganda, and was second and third in rank for Tanzania and Kenya,
respectively; cocoa beans (180100) were the leading export for Ghana and Nigeria in 2013, while black
tea (090240) was the most and second most important item for Kenya and Rwanda, respectively.
Horticultural products appear to be important for a number of our focus countries. For instance,
“other” vegetables (070990) and fresh cut flowers (060310) were the second and third most important
agricultural export goods for Ethiopia; fresh cut flowers (060310) were second most important for Kenya; and
fresh fruit such as oranges (080510), apples (080810), and grapes (080610) were the second, fourth, and fifth
ranked items for South Africa. Cashew nuts (080131) were the most important export item for Tanzania and
the second and fourth most important item for Ghana and Nigeria, respectively. A variety of processed food
items appears in the list including fish fillets, sugar, flour, vegetable oil, cigarettes, and alcoholic beverages.

The big hits change from one period to the next (Easterly and Reshef 2010) and a question arises
as to whether changes in the importance of agricultural exports are driven by new products. To answer the
question, we follow Kehoe and Ruhl (2013) in constructing the set of least-exported agricultural goods
which were originally either not exported or exported only in small quantities. Specifically, starting with
the smallest amounts of exports including zero, we add products to the set until the sum of their export
values reaches 2 percent of total export value in the initial period (“bottom 2 percent” items). To reduce
the chance that a good is typically exported but not exported in any one year (Kehoe and Ruhl 2013) and
to mitigate potential inaccuracy of the data reporting in the earlier years, we average each country’s
exports for the three earliest years for which the data are available in the Comtrade system.
Appendix Table A.2 reports the set of items that were bottom 2 percent in the earliest available
years, but made the top 20 list in 2013 for our focus countries. Except for Rwanda, the item that appeared
first in each list was either a horticultural or a processed agricultural product. For instance, while “other”
vegetables (070990) and fresh cut flowers (060310) were among the bottom 2 percent items at the turn of
the millennium in Ethiopia, they became the country’s second and third largest export goods in 2013.
Similarly, while bananas (080300) and almonds (080212) were among the bottom 2 percent goods for
Mozambique, they became Mozambique’s fifth and ninth most important agricultural exports in 2013.
The leading emerging processed goods include such products as palm kernel or babassu oil (151329) in
Ghana, cigarettes (240220) and cocoa paste (180310) in Nigeria, oil cake (230630) in Tanzania, and sugar
(170199) in Uganda. The emerging bulk products include oil seeds such as soya beans (120100) in
Ethiopia, sesamum seeds (120740) in Ghana, and other oil seeds (120799) in Tanzania and Nigeria,
perhaps reflecting rising demand for vegetable oils and animal feeds. For South Africa, in contrast, none
of the top 20 agricultural export items in 2013 came from the bottom 2 percent in earlier years.
One potential explanation for the low share of processed agricultural exports in Africa’s exports
on average is the relatively low income of most African countries. We know that a key feature of
consumer demand for food is that as incomes rise consumers shift from purchasing raw agricultural
products to products that embody more and more value-added services. To see whether Africa is
18
following that trend, or a distinctly different trend, we look at the relationship between real GDP and the
ratio of value-added in agricultural processing to value-added in agriculture, a relationship examined by
de Janvry (2009). Figure 3.3 reveals something close to a linear relationship between the ratio of value-
added in agricultural processing to value-added in agriculture. The African countries in the graph appear
broadly to follow this pattern. A dummy variable for Africa included in this regression failed to reveal a
significant difference between African and other countries. This suggests that the relatively low share of
agricultural processing in African economies reflects their relatively low incomes, rather than a specific
feature of African agriculture, such as the mix of commodities or consumer preferences.

Turning to the relationship between processed agricultural exports as a share of total agricultural
exports, we also find a positive relationship with real GDP, as Figure 3.4 shows. In this case, the
relationship appears to be nonlinear, with the rate of increase declining as incomes rise. However, there is

no indication either in the plot or from statistical testing that African countries are not following a similar
path to other countries.

4. TRADE AND PROTECTION PATTERNS
In this section, we use the Global Trade Analysis Project (GTAP) Database to allow us to capture both
trade and protection, and to prepare for the simulation analysis undertaken in the next section. Using
this database, we find SSA’s agricultural exports were $46.0 billion in 2011 of which $21.8 billion
(47.4 percent), $7.4 billion (16.2 percent), and $16.8 billion (36.5 percent) were bulk, horticulture, and
processed agriculture, respectively (GTAP 9 Database).4 In doing this, we build on the insight from
Jensen, Robinson, and Tarp (2010) that the impact of a trade regime on production incentives requires a
general equilibrium treatment, going beyond the impacts captured in either the nominal or the effective
rate of protection.
Figure 4.1 shows the destinations of SSA’s exports for total, bulk, horticulture, and processed
agriculture. This shows that the European Union (EU) was the largest destination for SSA’s exports,
taking 39.6 percent of SSA’s exports (37.3 percent, 42.4 percent, and 41.3 percent of bulk, horticulture,
and processed agriculture, respectively). Nineteen percent of SSA’s exports went to SSA, with processed
agriculture to SSA disproportionately accounting for 34.9 percent of SSA’s total processed agriculture
exports. The EU and SSA combined accounted for about three-quarters of SSA’s processed agriculture
exports, while its exports of bulk agriculture were more geographically dispersed. The South Asia region
absorbed 17.7 percent of SSA’s horticultural exports.
4 “Bulk” includes paddy rice (pdr), wheat (wht), cereal grains nec (gro), oil seeds (osd), sugar cane, sugar beet (c_b), plant-
based fibers (pfb), crops nec (ocr), cattle, sheep, goats, horses (ctl), animal products nec (oap), raw milk (rmk), wool, silk-worm
cocoons (wol), and fishing (fsh). Vegetables, fruits, and nuts (v_f) is used as a proxy of “horticulture.” “Processed agriculture”
includes meat–cattle, sheep, goat, and horse (cmt), meat products nec (omt), vegetable oils and fats (vol), dairy products (mil),
processed rice (pcr), sugar (sgr), food products nec (ofd), and beverages and tobacco products (b_t). See the GTAP website for a
detailed product breakdown: www.gtap.agecon.purdue.edu/databases/contribute/detailedsector.asp.

Columns 1 through 3 of Table 4.1 show the ad valorem equivalent (AVE) protection (Guimbard et
al. 2012) that SSA’s exports face, the AVE that SSA imposes against its imports, and the world AVE for
the purpose of comparison. The last four rows show the summary of AVE for agricultural goods. SSA’s
agricultural exports face an AVE of 7.0 percent in its export market (7.7 percent, 3.8 percent, 7.6 percent
for its bulk, horticulture, and processed agriculture exports, respectively), which is slightly lower than the
world average of 8.2 percent (8.3 percent, 5.2 percent, and 8.6 percent for bulk, horticulture, and processed
agriculture, respectively), perhaps reflecting its preferential access to certain developed countries including
the EU and the United States. The SSA’s own AVE against its agricultural imports of 12.2 percent was
about 50 percent higher than the world average.

Columns 4 through 6 of Table 4.1 show the AVE that SSA faces in the EU market, the AVE that
the EU imposes against its imports other than from SSA and the EU, and the EU’s average AVE,
respectively. SSA enjoys preferential access to the EU market. Its preferential rate for agriculture of 0.8
percent on average is substantially lower than the rate the EU imposes against its suppliers other than SSA
and the EU itself (7.3 percent). In particular, SSA appears to benefit from the lower preferential rates for its
processed agricultural goods (1.3 percent on average) relative to the AVE the EU imposes against other
suppliers (11.1 percent on average). The preference margins appear to be especially large for such products
as meat (1.9 percent versus 54.0 percent), dairy products (2.0 percent versus 23.9 percent), and sugar (1.2
percent versus 43.8 percent).
In its export markets, SSA faces tariff escalation within many value chains: paddy rice (1.2 percent)
versus processed rice (5.7 percent); oil seeds (7.0 percent) versus vegetable oils and fats (8.0 percent); sugar
cane and sugar beet (0.4 percent) versus sugar (9.1 percent); raw milk (0.0 percent) versus dairy products
(10.9 percent); and cattle, sheep, goats, and horses (1.3 percent) versus animal products not elsewhere
classified (2.6 percent), cattle, sheep, goat, and horse meat (33.7 percent), and other meat products
(5.0 percent) (column 1 of Table 4.1). SSA’s own AVE against its imports (column 2), intra-SSA AVE (last
column), and world AVE (third column) also demonstrate similar tariff escalation.
In 2011, about one-fifth of SSA’s agricultural exports took place within SSA. Figure 4.2 visualizes
intra-SSA trade for agricultural goods. The horizontal and vertical axes represent exporting and importing
countries, respectively. The southwest corner represents the trade within the Economic Community of West
24
African States (ECOWAS); the northeast corner represents trade for the Southern African Development
Community (SADC); and the countries belonging to the Common Market for Eastern and Southern Africa
(COMESA) tend to be in between. Several countries are members of both COMESA and SADC. We
observe that the agricultural trade in SSA tends to occur in the same regions. The ECOWAS and the
COMESA/SADC countries rarely trade with each other for their agricultural goods (except for South
Africa, which exports agricultural goods to some ECOWAS countries). The last column of Table 4.1
reports the AVE for intra-SSA trade. Despite the presence of a number of trade blocs within Africa, AVE
protection for agricultural goods within SSA remains relatively high at 10.1 percent (higher than the world
average AVE of 8.2 percent), with an especially high AVE for processed agriculture, at 12.6 percent.

5. SIMULATION SCENARIOS AND RESULTS: TRADE EFFECTS
In this section, we use the standard GTAP model (Hertel 1997), with the patterns of trade and protection
discussed in the previous section, to analyze the comparative-static impacts of different potential policy
reforms. By simulating the removal of protection, these experiments are intended to assess the effects of
the existing distortions on SSA’s agricultural trade rather than to evaluate specific impacts of any actual
trade reforms.
As this paper focuses on agro-processing and horticultural exports, the purpose of the simulations
is to measure trade effects.5 Simulation 1 considers the effects of removing tariff escalation in SSA
partner countries. Simulation 2 focuses on the loss of preferences in the EU. Simulation 3 considers
agricultural trade reform within major trading blocs in Africa. Simulation 4 considers the impact of higher
productivity in agricultural processing in Africa. Finally, Simulation 5 considers the impacts of SSA
countries removing all AVE protection, including protection of manufacturing and resources goods,
against all its trading partners.
Column 1 of Table 5.1 shows the simulation result from eliminating tariff escalation by SSA’s
partner countries, reducing their AVE protection for processed goods to the levels of unprocessed goods
in the same value chain identified above (for example, lowering the AVE rate of processed rice to the
level of paddy rice) (Simulation 1). SSA’s exports of processed goods increase by 114.3 percent while its
bulk and horticulture exports decrease slightly by 4.6 percent and 3.5 percent, respectively. Overall,
SSA’s agricultural exports would increase by 39.0 percent.6 These results show that tariff escalation in
external markets poses substantial barriers for SSA’s exports of processed agricultural products. While
SSA receives duty-free access from some partners such as the EU (and it is likely that the preferential
5 Since the model assumes full employment, further studies are required to assess employment effects. 6 The 5,056.8 percent increase in the exports of cattle, sheep, goat, and horse meat (cmt) appears to reflect initially very high
AVE protection imposed by some partner countries (for example, Norway) against SSA’s exports of this category. One caveat
on this exercise is that the AVE protection used in this paper does not include sanitary and phyto-sanitary (SPS) requirements
and that SPS issues frequently need to be addressed for new exports to take place. For instance, focusing on the case of foot-
and-mouth disease (FMD) in southern African countries, Scoones et al. (2010) report that the presence of FMD is a major obstacle
for these economies to gain access to international markets.
27
access creates incentives for processing in SSA), there appears to remain scope to increase agro-
processing exports further resulting from the removal of tariff escalation by other trading partners. The
dramatic increase in exports of processed agriculture from SSA under Simulation 1 suggests that the
provisions in the Doha Agenda proposals on reducing tariff escalation (WTO 2008, 18) may have very
favorable effects on exports of processed agricultural products from Africa. They make a case for policy
makers focusing on this issue in future trade negotiations.

Simulation 2 explores what happens if the SSA loses its preferential access to the EU market for
its agricultural goods, with the EU increasing AVE protection against SSA from the preferential rates to
those that the EU imposes against other suppliers (columns 2 and 3 of Table 5.1). SSA’s agricultural exports
to the EU would decrease by 14.9 percent, which would lead to a reduction of its overall agricultural exports
by 5.5 percent. As the EU’s AVE protection for processed agriculture against nonpreferential suppliers is
especially high, the loss of preferences would result in a sharp reduction in SSA’s exports of processed
agricultural products—by 29.9 percent to the EU, and by 12.2 percent to the world.
Simulation 3 investigates the impacts of ECOWAS, COMESA, and SADC countries reducing
their AVE agricultural protection against each other to zero within their regional arrangements (columns 4
and 5). The simulation is partly motivated by the potential for regional agricultural trade to contribute to
food security by enhancing the resilience of Africa’s food supply system (Badiane, Makombe, and
Bahiigwa 2013). The result shows that the agricultural liberalization within these trade blocs combined
would lead to the expansion of intra-SSA agricultural trade by 28.8 percent, while SSA’s total agricultural
exports to the world would increase by 5.1 percent. The results of this simulation reflect the effects of
removing agricultural barriers in general, and the tariff escalation within such barriers, and hence result in
more rapid growth in exports of processed agricultural products than in total agricultural exports
(37.6 percent and 13.1 percent increase in processed agricultural exports to SSA and to the world,
respectively). They illustrate the extent to which protection within Africa discourages export of all
agricultural items.
29
Simulation 4 explores what would happen if SSA countries were to increase total factor
productivity in processing of agricultural goods by 10 percent (sixth column of Table 5.1). This
simulation ignores the costs of bringing about such productivity gains and is intended to help identify the
areas in which the gains are likely largest and hence to identify priority areas for reform. The results
reveal that SSA’s exports of processed agriculture would expand by 30.3 percent; its exports of bulk and
horticulture goods would decrease slightly by 2.5 percent and by 1.9 percent respectively as some goods
are processed before being exported after transformation; and its overall agricultural exports would
expand by 9.6 percent. This simulation result is consistent with the literature on high productivity
associated with exports and highlights the importance of improving the productivity of agricultural
processing activities for expansion of these exports. This simulation understates the long-run impacts of
raising productivity in these sectors because the modeling framework that we use looks only at static
gains and does not allow for the emergence of new activities. Thus, it misses the extensive-margin impact
of increases in productivity, where higher productivity may cause new export activities to take place.
Simulation 5 involves complete removal of AVE protection against SSA’s imports including
nonagricultural goods. Perhaps not surprisingly, it leads to a much larger increase in total exports than any
of the other simulations (last column in Table 5.1). Because processing agricultural products is typically a
low-margin activity, we had anticipated that it might also result in a large increase in the share of
agricultural exports shipped in processed form. Three effects on processing exports from removing all
import protection can be anticipated: (1) the removal of each country’s own tariff escalation is likely to
reduce production of processed goods for domestic markets; (2) the removal of tariff escalation by
African partners increases opportunities for processing; and (3) reductions in the costs of inputs used in
processing would be expected to expand processing for both domestic and export markets. The model’s
results point to an increase in processed agricultural exports relative to bulk and horticultural exports,
suggesting that the reduction in production costs and the increase in market access opportunities would
30
outweigh the reduction in incentives to process for domestic markets. However, the increase in
agricultural exports is not much larger than the increase in overall exports.

6. POLICY QUESTIONS
The decision on whether to export a raw agricultural product should still be based solely on the
economics of the value-adding process. If, for instance, coffee may be exported in fresh or roasted form,
the decision on whether to undertake the roasting stage should depend only on the costs and returns
associated with undertaking that stage. The “great unbundling” (Baldwin 2006) means, however, that
other countries may well have become competitors for the bean-producing country in roasting the coffee.
Naïve calculations that consider only the value of the roasted beans relative to the value of the raw
beans—without considering the costs of the processing phase—are insufficient as a basis for deciding
whether to undertake the processing phase in the producing country.
In general, it seems sensible for policy makers to delegate to producing and processing firms the
decisions about whether to undertake particular stages of production, and to focus on providing an
enabling environment in which producers may be able to take advantage of those opportunities that
generate positive value-added. Only producing firms are likely to have the information needed to assess
whether it will pay them to undertake additional processing. However, in the unbundled trade system, it is
now much more important for governments to keep channels of communication open to identify when
specific constraints that might be relaxed are preventing the emergence of particular processing stages in
the country. If there are, for example, high tariffs on inputs needed in the production process, this may
turn out to make it uneconomic to process the good domestically even though doing so would add value
at world prices. Another important source of elevated costs is weaknesses in infrastructure, such as
transport, electricity and water, or excessive costs of customs clearance, that may make otherwise high-
return activities privately unprofitable. A key step for governments is to identify where they can reduce
some of these costs to enable firms to undertake processing operations that would be economically
worthwhile?
Vulnerability to excess costs is particularly acute for processing activities because those activities
frequently operate on small margins relative to, say, production of a traditional export. Traditional exports
32
such as coffee frequently embody an especially large share of rents that can be dissipated—particularly in
the short term—without the activity shutting down. Consider, for example, the decision on whether to
export live cattle or chilled, boxed, deboned beef. The livestock herder is likely to be cash poor and
willing to sell cattle even if the price is quite far below the expected level and to be little affected by
distortions in input markets. By contrast, the returns from slaughtering, boning, and packing beef are
likely to be quite small relative to the cost of the animal and the needed intermediate inputs. If, for
example, the beef from a $100 animal is valued at $150 on the world market and intermediate inputs and
labor costs account for $35 of the $50 difference, increases in the cost of intermediate inputs or labor
could easily wipe out the needed returns from processing and either block the emergence of this activity
or cause it to shut down.
If we find that high tariffs and other charges on intermediate inputs result in negative value-added
(at market prices) in at least some processing activities, the disincentive to undertaking these activities
may result in economically desirable processing not being undertaken. If the government wishes, it may
deal with these problems either by reforming its tariffs and customs regimes or by specific export-focused
policy responses such as providing duty exemptions on intermediates used in the production of exports.
Responses of this type would not require negotiations with trading partners.
Another potential cause of failure to undertake desirable processing actions arises from
distortions imposed by trading partners. A key challenge for processing in developing countries comes
from tariff escalation in importing markets. In this situation, the tariff in the importing market is low on
raw materials, higher on intermediates, and highest on final consumer goods. This policy option creates—
and typically is intended to create—incentives to undertake processing in the importing country and to
discourage processing in the exporting country. Such incentives could be countered by the exporting
country, but this action would surely be difficult to undertake successfully. However, information on the
extent of such tariff escalation is likely to be useful background for tariff negotiations.
33
The impact of tariff escalation is likely to be turned on its head when considering exporters that
have access to effective preferences for raw and processed products. If we assume that processing a good
adds 20 percent to its initial value, then a tariff margin of 20 percent between the raw and the processed
form of a product creates a 100 percent effective rate of protection on the processing activity. Under a
nondiscriminatory tariff regime, this assistance is provided to processors in the importing country. If this
tariff applies against imports of most producers but some small producers receive a tariff preference, the
20 percent effective rate of protection may be available to processors in the exporting market.
Comparison of the mix of processing in preference- and non-preference-receiving exporters may provide
some indication of the effectiveness of the preference regime in creating incentives for additional
processing in exporting countries.
Developing new exports from Africa is both vitally important and very challenging. Some of the
barriers that have been identified—such as geography and landlocked status (Freund and Rocha 2011)—
are inherent, but their effects can be addressed by adequate policy reforms and associated investments.
For instance, in examining the effect of trade times on Africa’s exports of new products, Freund and
Rocha (2011) report that reducing inland transit times significantly boosts exports (especially for time-
sensitive agricultural exports) and suggest the importance of investments on inland transportation and
infrastructure. Bouët, Cosnard, and Laborde (2017, fig. 2.4) show that the costs associated with time for
border and documentary compliance are high especially for agricultural products for many African
countries.
The stylized fact emerging from the recent literature on exporting firms that a small number of
highly productive firms generally dominate exporting activities (Bernard et al. 2007) would seem to allay
the concerns expressed by Hausmann and Rodrik (2003) that firms investing in costly discovery of
successful exports lose the returns from export success through entry of copycat firms. In this situation, it
seems possible, and perhaps vital, to create a situation that stimulates firms to invest in discovery of new
opportunities. Approaches to creating incentives for innovative exports by providing protection to sales
34
on the domestic market appear to have little applicability in Africa. Large domestic markets for these
products only rarely exist, and even if they do, they are likely to become saturated relatively rapidly,
leaving innovators with low returns on their investment. While export subsidies for developing countries
are only loosely constrained by World Trade Organization (WTO) rules (Creskoff and Walkenhorst
2009)—and are almost unconstrained for least developed countries and countries whose per capita GDP is
under $1,000 in 1990 dollars—the fiscal costs of such export subsidies are likely to be very high. Fiscal
problems are likely to arise with the third policy option considered by Hausmann and Rodrik (2003,
630)—the provision of grants and subsidies to chosen firms. If such subsidies are large enough to make a
difference, they are likely to be very costly. Further, Farole (2011, 173) finds that such incentives are
associated with poorer performance in African economic zones.
In contrast, the approach of providing a relatively level playing field on which exporters can
experiment in order to identify successful exports seems promising. One approach to providing an
environment for experimentation is to allow exporters to access intermediate inputs for use in production
of exports at world prices. In China, duty exemptions were a central feature of its economic reforms,
allowing exporters to use imported materials and to increase processed exports in a wide range of labor-
intensive activities (Ianchovichina 2004). Other successful exporters of industrial goods—for instance,
Cambodia, Mauritius, Tunisia, and Vietnam—also established a “free trade regime for exporters” through
a variety of mechanisms such as tariff exemptions, duty drawbacks, and rebates of indirect taxes
(Newman et al. 2016a).
A duty exemption or duty drawback system reduces the burden imposed by a country’s own
protection regime and decreases the inefficiency associated with the country’s trade regime by
eliminating the negative effective rates of protection resulting from exporters having to pay import duties
on their intermediate inputs while receiving no protection on their outputs. Given the low margins
inherent in many processing activities, this problem of negative protection can frequently explain the
absence of many highly productive export activities. Duty exemptions, under which duties are waived on
35
imported inputs subject to subsequent verification of their incorporation in exports, are strongly preferred
by exporters to duty drawbacks where duties must be paid and are—in principle—refunded on export of
the final good. A related export facilitation mechanism needed in countries applying a value-added tax
(VAT) is a refund of the VAT paid on intermediate inputs used in the production of exports. This is an
inherent feature of any destination VAT and not a special export processing incentive. It, like a duty
exemption arrangement, is fully consistent with WTO rules on subsidies (Creskoff and Walkenhorst 2009).
Duty exemptions and VAT refund mechanisms are frequently part of more comprehensive export
promotion mechanisms such as special economic zones (SEZs) (Farole 2011). SEZs typically involve
other features, such as improved infrastructure, and a different regulatory environment from the rest of the
economy. Frequently, this environment is designed to attract foreign direct investment. Collier and Page
(2009) point to strong advantages if they are located in geographically favored regions near infrastructure.
Farole (2011, ch. 8) finds that African zones have encountered difficulties in a number of areas, including
unreliability of power supply relative to Asian zones, slow customs procedures, and wage rates that are
high relative to labor productivity.
The high wage rates relative to productivity seem surprising given the very low incomes
prevailing in much of SSA. This may reflect some sort of insider–outsider distinction that results in
relatively high wage rates for a relatively small volume of output and level of employment. Using
Farole’s (2011, table 8.2) numbers on output per person in the zones and adding 2014 GDP per person,
Table 6.1 shows that wage rates in the African SEZs are almost 90 percent of wage rates in his four
comparator countries, even though GDP per capita, and, hence, likely the opportunity cost of labor to the
zone, is only 42 percent of the level in the comparator countries. The difference is even more stark with
the two highly successful Asian comparators—Bangladesh and Vietnam—where wages average less than
half the African rate even though national incomes are higher.

Following his detailed consideration of SEZs in Africa, Farole recommends that African policy
makers consider processing of agricultural and resource exports in addition to labor-intensive
manufactures that have been the focus of export processing activities in Asia. It seems to us that this may
be a part—but surely only a part—of the solution to the problem of stimulating a takeoff of new exports
from Africa.
Drawing on the lessons of recent decades, it seems more likely to us that deep, sustained growth
in exports from SSA will result from policies that provide as much scope as possible for entrepreneurs to
search and discover, in the sense suggested by Hausmann and Rodrik (2003), the products that will be the
highly successful exports of the future. Making sure that a wide range of potential exporters have access
to the intermediate inputs they need seems likely substantially to expand the range of products with which
potential exporters can experiment. Current, generally closed, SEZs do not seem to have worked very
well in doing this, despite the provision of duty exemptions on intermediates, improved infrastructure,
and fiscal incentives. Perhaps one way to overcome these challenges is to draw from China’s experience
and to extend the most important of these incentives—the duty exemptions for intermediates used in the
production of exports—to export processors of all kinds throughout each country. Once processors of
37
agricultural products, along with producers of other potential exports, have access to intermediates at
world prices and to labor and other inputs at domestic prices, their experimentation is likely to lead to
identification of exports that will become the future big hits and mainstays of higher levels of future
exports. As argued by Newman et al. (2016b), it is not enough just to improve the investment climate—
which nevertheless remains a high priority—but what is needed is a broader push for export development
of the type seen in countries such as Vietnam and Cambodia.

7. CONCLUSIONS
The recent focus on the potential for agricultural processing and horticultural exports as growth engines
for Africa appears to be driven in part by pessimism about the prospects for growth of manufacturing
exports of the type that have been so stunningly successful in driving export growth from many Asian
countries. Key questions include whether this pessimism is warranted, and whether the agricultural
processing and horticultural exports can become the engine of growth so much needed to promote African
development.
New developments in economics have given us new insights into the growth of exports that are
highly relevant for analysis of this question. We now know that exports of any country tend to be
dominated by a relatively small number of products, often exported to a relatively small number of
markets (Easterly and Reshef 2009, 2010), and frequently by a small number of highly productive firms.
This reduces the concerns that have been expressed by authors such as Hausmann and Rodrik (2003)
about the risk that innovators will not be able to recoup their fixed costs of discovery because of excessive
entry of imitators.
When we look at the pattern of exports from African countries, we find that the share of
agricultural exports has declined to around 10 percent of the total, somewhat less than the 12 percent of
exports accounted for by nonfactor services. This is a very small share on which to build if the goal is to
stimulate dramatic growth in exports through exports of horticultural or processed agricultural products.
Within agricultural exports, the share of traditional, bulk agricultural exports has fallen sharply, from 60
to 42 percent, although this is now twice the share of such exports in global trade. Where Africa does
stand out is in the share of horticultural products in total exports—more than 22 percent of agricultural
exports in 2014 as against 12 percent for the world as a whole.
The relatively low—but rising—share of processed agricultural exports from Africa may reflect
the relatively low incomes in African countries. When we plot the share of value-added of processed
agriculture relative to total agriculture in Africa against real incomes, we find no need for an Africa-
39
specific explanation. Most of the observations are distributed around a rising trend. When we look at the
share of exports, African exports of processed products relative to total agricultural exports also seem to
follow the same broad relationship as other countries, in this case a quadratic response to income growth.
Simulation analysis is used to examine the response of processed agricultural exports from Africa
to changes in protection rates and productivity growth in processing. The results suggest that tariff
escalation in export markets has powerful impacts. Cutting protection on processed agricultural products
in export markets would substantially increase exports of processed products from Africa. Cutting
agricultural protection within main African trade blocs and extending liberalization to all the trading
partners and to all the goods would similarly increase exports of processed agricultural products.
Our overall assessment is that increased exports of processed agricultural products could be a
worthwhile contributor to an overall upturn in African agricultural exports. Horticultural products could
also contribute to such a turnaround. However, our view is that policy makers should think much more
broadly, in a way that the export promotion strategy for these products is consistent with the development
of other export-oriented goods and services. As trading costs in Africa remain relatively high, including
import duties, transportation costs, documentary and border compliance costs, and other nontariff
measures (Bouët, Cosnard, and Laborde 2017), policy reforms and associated investments appear to be
necessary. For instance, one of the promising ways to encourage a surge in agro-processing and other
exports would be to reduce the cost of intermediate inputs generally. Reducing this disadvantage for
exports—ideally by reducing protection, but perhaps initially by ensuring that all exporters have access to
intermediates at world prices—is likely to stimulate growth in a wide range of exports as entrepreneurs
discover what exports best use the country’s skills and resources.
